Tracking force

Tracking force is the amount of downward pressure the stylus exerts on the record groove, measured in grams and set using the tonearm's counterweight. Every cartridge is designed to perform within a specific range of tracking force given by its manufacturer, rather than an arbitrary number a listener picks.

Getting this right matters because too little force lets the stylus skip or bounce out of the groove, especially on loud or heavily modulated passages, while too much force presses the stylus harder into the vinyl than needed, accelerating wear on both the stylus and the record over repeated plays. Neither too light nor too heavy actually protects records better, contrary to what some assume, since the cartridge's spec range represents the tested sweet spot for that stylus and suspension.

A tracking force gauge gives a far more accurate reading than trusting the numbered dial on a counterweight alone, since those dials can be slightly off from the factory. Always check the cartridge manufacturer's recommended range rather than a generic number found online, since it varies by model. A common mistake is setting tracking force once and never rechecking it, when a cartridge that has been bumped, swapped, or reinstalled should always be reverified before regular listening resumes.
